Specification of Letters Patent Patented Feb. sew 1910.

Application filed July 3, 1909, Serial N0. 505,902.

Bristol City, in the State of Virginia, have invented a new and useful Coke-Oven Door, of which the following is a specification.

This invention has reference to improvements in coke oven doors, although the door forming the subject matter of the. present invention may be used for furnaces, kilns, and in other places where the great.

over the coke oven door shown and described in Letters Patent No. 882,365 granted to me on March 17, 1908.

The present invention relates more par; ticularly to the hinge structure and manner of hanging the door. and that portion of the door subjected to the heat of the furnace may be constructed in a mannersimilar to that described in the said Letters, Patent. i

In accordance with the present invention rovision is made for counteracting warpm of the door orchange. in shape of the 00(6 oven opening or dlsplacement of the hinges, so that the door may be brought into proper engagement with the coke oven open mg, and since it is customary to use a number of doorsfit closely and so properly close the opening irrespective of lack of proper alinetnent of the supports initially or because of warping or other causes affecting the hanging of the door at a later time.

The invention will be best. understood from a consideration of the following detail description taken in connection with the accompanying drawings forming a part of this specification in which drawings- Figure- 1 is an elevation partly in section of a portionof'a coke oven opening showing 'two doors in place therein. Fig. 9 is edge view of one of the doors in place in the coke own opening. l ig. 3 is a plan view of one of the doors in place in the coke oven opening with the hinge rod shown in section. Fig. 4 is a view showing the adap'tabilitrof the hiu 'e or hanger structure for compensating or want of proper alinement of the parts.

lteferringto the drawings, there is, shown a small portion of a coke oven t'which may be taken as typical of any suitable coke heat generated I mg The present invention is an improvement for each opening. the arrangement )5 such that the doors may be made to l l l protect the ting of the ring is formed with to the frame 7 neroai s 12 and l3 respectively.

oven and there is also shown a portion of an opening leading to the interior of the oven. In sin-h ovens it is customary to pro vide two sets of doors one above the other, the doors of one set opening, to one sideof the opening 2 and the doors of the other set opening to the other .sule of the opening 2 In the drawings there is shown an up or door 3 and a lower door 4, it being llllt erstt'iod that two like doors are employed to complete the closure for the coke oven open- The structure of the doors does not in itself enter into the present invention and the saiddoors may therefore be considered as being made in the manner set forth in the aforesaid Letters Patent.

The door has secured thereto a ring 5 by bolts or other means embedded inthe mate rial of the door so as to be protected from the heat of the interior of the furnace and this ring 5 is spaced away from the door by legs, as: shown, to form an air space between the ring and the outer face of the door to from the action of heat. The outer face two cars (3 in spaced relation one to the other and disposed one opposite the other in a line diametric to the ring Through these cars there is passed a bolt 7 and this holt also passes through two cars 8 project ing from opposite corners of a rectangular frame 9 made up of two longitudinal members and two end cross members beyond one of which the ears 8 project and be'yond the other of whichother ears 19 project. There also prov; fed another frame 11 similar k ,0,thnt is, it is made up of two longitudinal members and two end cross lneit'ibers and from this frame project cor- The frame 11 is larger than the frame 9 both in height and length and the cars 12 are sutiiciently spaced to receive the ears 10 between them and these cars are traversed-by a pivotbolt 14. The cars 13 are pivoted upon an up right rod 17 secured to the coke oven 1 on the length of the car which till llli.)

tlo

is lateral to the len -'th of the frame 9. The outer surface of one 1 car is providedwith a series of corrugations 17 extending in the direction of the length of the frame 9 and these corrugations are adapted to receive the ends of a curved Washer 18 through which the bolt T extends and which are engaged by the head of the belt at one end of the latter and by a nuta )plied to the other end of the bolt These washers l8 serve to position the boltyT with relation to the slots Ill and consequently position the doorswith relation to the frame 9.

The fltllll6 9 and 11 form a double hinge support for Qttt'll door so that 'when a door is in position in the opening 2 the frame 9 may be substantially parallel with the side wall of the opening while the frame 11 is substantially parallel with the face of the kiln. By this means the door may be well seated in the opening 2 without undue projection of the frame 11 beyond the face of the kiln;

When it is desired to remove the door,

from the opening 2 it may be readily swung around on the pivot rod 15 until both frames 9 and 11 are in alinenient and parallel with the outer face of the kiln While the door .may he 'turnedparallel with the frame 9 and lie flat against the outer face of the kiln.

Because of the corrugations 17 and the elongated slot 16, the bolt 7 may be set near one end of one of the ears 8 and near the other entl of the other car 8 and so tilt the door about an axis cutting the belt at right angles. By this means the door may be made to fit accurately in the opening 2 whether the parts sustaining the door were initially improperly adjusted or whether they afterward got out of adjustment because of the outer doors or both,

warping of the kilnwalls. The pivot bolt 7 permits "the swingin of the door thereabout for the accurate acing ofthe door in the oven opening and i or brmgin the door flat against thekiln wall when the door is swung away from the ovenopening, while the slots ltiand washers 18 permit the moveonan axis at right an les d oor ment of the door to the length of the bolt 7 to bring thev mto accurate relation to the opening or to if necessary. What is claimed is:

1. A coke oven door having a hinge pro vided with ears formed with elongated slots and eaclrcorrugated or grooved on one face, a pivot bolt traversing the slot, and curved Washers on the bolts entering the grooves or corrugations and thereby positioning the bolt.

2. A coke oven door having a hinge provided with ears formed with elongated slots and each corrugated or grooved on one face, a pivot bolt traversing the slots, curved washers on the bolts between the grooves or corrugations and thereby positioning the bolt, and a dooncarried member pivoted to the bolt/between the slotted ears.

3. A coke oven door provided with a doorearrying member having spaced cars, a hinge member provided at one end with ears extending laterally and each having an clon gated slot in the direction of its length and. corrugated on one face, a pivot bolt traversing the ears on the door and the slots in the ears on the hinge member, curved washers carried by the bolt and engaging in the corrugations on the face of the slotted ears. and another hinge member having ears exterior to the end of the first-named hinge member remote from the slotted ears, a pivotholt; traversing the matching ears of the two hinge members, and a pivot support; for the second-named hinge member remote from the end carrying the first-mulled hinge member.

A coke oven door having a ring secured thereto at a central point and spacedaway fiihn the outer face of the door for the circulation of air, said ring being formed with diametrically disposed ears, a, pivot' bolt extending through the ears, and about which bolt the door is movable, a hinge for the door having ears 'with elongated slots traversed by that pivot bolt and having each ear formed on one face with'eorru ations at ri ht angles to the length of the s 0t, and was? ersed testimonythat 1 claim the foregbing' as my own, I have hereto alfixed my signature lers tron by the bolt and engaging the eorrii 'gation si
